Specification of Letters Patent.

Patented July 21, 191d.

Application filed December 31, 1913. Serial No. 809,773.

To all whom it may concern:

Be it known that I, GERARD T. Snonn, a citizen of the United States,residing at Revere, in the county of Suffolk and State of Massachusetts,have invented an Improvementin Window-Locks, of which the following is aspecification.

This invention relates to certain improve-- ments in window fasteners,and, more particularly, to window fasteners which are adapted to lockboth the upper and the lower window sashes in a partly open, as well asin a closed position.

The object of my invention is to provide a fastener of simpleconstruction, which is adapted to be readily applied to the window sashand casing and with which either the upper or the lower sash may besecurely locked against outside interferenceeither in a partly open or aclosed position.

A further object is to provide a device of the above described characterin which a movement in one direction will simultaneously lock both theupper and the lower sashes in the particular positions to which they areadjusted,- and a corresponding movement in the opposite direction willre lease them.

Another object is to provide a device of the above described characterwhich may be readily applied to any ordinary window and which may beused at either side of the window casing by merely reversing theposition of some of the parts.

I accomplish these objects by the means shown in the accompanyingdrawing, in which,

Figures 1 and 2 are horizontal sectional views of a window casingprovided with a locking device made according to my invention, andarranged in position of use. Fig. 3 is a vertical sectional viewthereof. Figs. 4: and 5 are longitudinal sectional views of the lockingdevice showing the same in the locked and unlocked positions of use.Fig. 6 is a plan View of the device with the parts arranged for use atthe lefthand side of the window casing. Fig. 7 is a plan view of thebase-plate.

In the drawing a indicates the window casing having the usual runwaysfor the lower sash b, and upper sash c, said runways being separated bythe usual parting bead d.

According to my invention I provide a base-plate c which is adapted tobe fastened by screws, or any other suitable means, to the upper end ofthe lower sash, the length of said plate being approximately equal to,or no greater than the width of the sash, and said plate being arrangedtransversely of the sash as shown. Said plate is provided with alongitudinal slot 6 and a screw 7 is mounted in said slot, the undersides of which are rabbeted to receive the head of said screw. A lockingbolt 9 is mounted on the plate 6, and said screw j is arranged to passthrough an aperture in the middle portion of said bolt. A nut it isthreaded on the upper end of screw f, and is adapted to clamp the boltonto the plate 0. Said bolt g is provided with an upper sash-engagingendportion 9 which extends longitudi nally of the bolt and in thedirection of the slot 0, and a transversely extendingparting-bead-engaging projection 9 which is arranged adjacent saidprojecting end-portion and extends at right angles thereto. The oppositeend of the bolt 9 from its sash engaging portion g is provided with areversible dog having oppositely disposed lugs 70 and 7%, either ofwhich, (according to which side of the bolt is arranged upperinost,) isadapted to enter the slot 6 and engage the outer end thereof to preventmovement of the bolt back from looking position, as shown in Figs. 1 and4, and also to hold the bolt in open position, as shown in Fig. 5, isdesired.

The upper sash c is provided with a series of recesses 0 which arearranged in alinement with the sash-engaging portion 9 of the bolt, indifferent positions of the sash, each recess being preferably providedwith a metallic lining 2', as shown. The parting bead d is provided witha series of notches cl arranged in position to permit the transverseprojection g to pass therein and said notches are preferably metal linedor protected by means of a U-shaped clip j, which is adapted to beinserted therein and to be fastened in position by a screw m whichpasses through the parting bead into the casing.

In Figs. 1 to 5 the parts are shown as arranged for use at the righthand side of the window. f it is desired to lock the upper and the lowersash to the casing it is merely necessary to slide the bolt, from theposition of Fig. 2, toward the upper sash, and to the position ofFig. 1. This the bolt cannot be moved back without lifting the dog outof engagement with the plate. The nut h is preferably tightened when thebolt is in locked position to clamp the bolt firmly onto the plate andthus providean additional means to prevent outside interference.

If it is desired to use the device on the left-hand side. of the windowsash it is merely necessary to remove the nut it, turn the boltthe-other side up and then reinsert the screw; v

The above described device is of simple construction as the twoprincipal parts the base plate and bolt-may be made by a casting orsimilarly inexpensiveoperation and require very little machine work, sothat. the whole device may be made at a comparatively low cost for sucha device, and it may also be readily applied to any ordinary window atsmall expense.

I claim I I In combination with a window casing having a parting beadand upper and lower window sashes movable at opposite sides of saidparting bead, a base plate mounted on the upper end of said lower sash,and having a slot extending perpendicularly with relation to said uppersash, a screw movably mounted in said slot, a locking bolt adapted to beheld either sideup on said plate and through which said screw is passed,a nut on said screw for clamping said bolt to said plate, said bolthavingan end portion, ei tending longitudinally with relation to saidslot, and a transversely extending side portion, said end and sideportions being respectively arranged to engage the upper sash and theparting head when the bolt is moved toward said upper sash, and saidbolt having oppositely disposed projections ar ranged to engage saidplate and lock said bolt against longitudinal movement in either of itspositions of use, substantially as de scribed.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
